Getting cors error even after following all the steps you have mentioned on readme #18

Hello, I followed all the steps for firebase on your readme, but Im still getting a cors error. "Access to fetch at 'xyz' from origin 'http://localhost:3000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled." Can you please help me with this?

Some people were having issues with Firebase, usually with POST requests.

The easiest way forward is probably to use fly.io instead. Give that a go and let me know how you get on.

Oh actually I realized that the issue is that I did not add "allUsers" as permission to call my firebase function. After I added that, It worked fine atlease from my localhost:3000 port, however Im still facing issues when I actually try to call it from the website that I have hosted on netlify. Nevertheless, thanks for this repo, it is really helpful but you might want to add that additional section for the firebase readme to enable the permissions

Yeah no problem. Is that allUsers permission that you have set from the Google Cloud Platform dashboard or where are you referring to?

Also did you attempt to deploy from fly.io or not? If the latter, I would really recommend giving it a go as it should only take a few minutes and could solve your issues.
